Wanted to post this here in the hopes that as many people see it as possible. I recently put my truck back on the road after a major repair. I drained the tank and put in a full tank of FRESH GASOLINE. It was just simply amazing how much better the truck ran compared with how it ran before the fresh gas! Much has been written about modern ethanol laced gasoline, and how quickly it deteriorates. After 30 days this new stuff gets pretty rank!! I'm posting this to say that if you're engine is performing poorly I STRONGLY SUGGEST that you drain your tank and then put in lots of fresh gasoline and see if that doesn't cure your problems. My truck has never run better and I didn't have to do a thing other than put in fresh gasoline!
Hope this helps some of you guys pulling your hair out trying to figure out why your truck isn't running good.
